Chris,
I'm open to BSD or MIT as well. Looking, I see that SQLAlchemy is
MIT-license, so I can re-license it to that.

Thanks to Mike for his feedback and encouragement to post this on PyPI.
I've addressed the weaknesses he mentioned and added more features and
tests. Comments and feedback are welcome. Enjoy!

I'm having trouble telling an orm query which table is the main
table when I
only use a single column from the main table and it is wrapped up in

function. It's almost like SqlAlchemy can't see that I am using a
column from
that table because it is inside of a function::

Thanks, that worked.

I have a table 'table', with a column, 'stamp', that has an onupdate
clause onupdate=datetime.now.
I am trying to update table.otherColumn, and I don't want table.stamp
to be updated with the latest time.
I saw one discussion about overriding onupdate here:
The underlying column returns a Decimal object when queried regularly,
and when summed as follows:
select([ mytable.c.hours ])
Decimal(1.0)
select([ func.sum(mytable.c.hours) ])
Decimal(1.0)
...but when I sum it w/ an if statement, it returns a float:
select([ func.sum(func.if_(True,

This query is actually being used for a subquery. Table 'Time' also
has a column 'employeeId', which translates to an orm attribute of
'emp'. When I add Time.emp to the columns of this subquery, all
complains about invalid syntax when it encounters the

How can I set this chain of functions as a default? Is there some sort
of SQL literal function that I could use? I tried using the literal
object, but it of course escapes whatever the value is which does not
work.
